i holes `F as the ease may require. The plate G, is readily adjustable to a plumbline, and

`also may be easily set so as to give any de4- sired rake to the saw. The dotted line in Fig. '2 indicates the position of the head block on which the log rests. VVhatI consider novel in this arrangement is the mode `of holding and `guiding the saw by means of a` thinguide plate immediately behind andn the` same plane with it, and thusfollowing ;it through the log, dispensing With fender posts and `vvays and heavy vibrating y frames, and also, as the plate is made thicker than the saw, keeping it clear of the logs and boards, and protecting it from pinching,

`and diminishing the liability to run Which `res`ults"from the crowding of the stuff against it. I say dispensing with fender posts,\be`cause, although shown in the drawing, they are by no means necessary, as i there is nothing tomove in them, and the guide plate can be easily fixed and strained "to sill and beam of the building, or in other Ways.

The1 advantages vthus secured, in respect to `simplicity and cheapness of construction, and comparative freedom from rack and jar, are obvious, and need no particular explanation.

and following it through the log, Whether the saine be used `by itself, or inconnection 1' With `any other means of holding and guiding the saw. f
